Abstract: 168,440. Bell, R. T. June 11, 1920. Rotary disc and like apparatus.-A weighing- machine is provided with a rotary display disc bearing advertisements and adapted to be operated by a spring motor which is controlled by the raising and lowering movements of the platform. The person .on the platform operates a lever 46 which releases a lever 32 normally locking the weighing-device by engaging with the hooked end of the spring-controlled rack 10 gearing with the index pinion 11 and connected with the platform by the rod 4: The lowering of the platform carries with it a piece 52 having a pair of escapement fingers 48, 49 adapted to alternately engage with a pin 50 on a pinion 25 in the train of gears operated by a spring motor 26, the last of the train being a pinion 22 mounted coaxially with the index pinion 11 and carrying a disc with segmental advertisements, one of which is visible through a glass screen arranged over the weight disc. The lowering of the piece 52 releases the pin 50 from the hook finger and liberates the spring motor, and the display card is rotated until the pin 50 is arrested by the hook 49. When the persons steps off the platform the display card is further rotated owing to the using of the piece 52 and release of the pin 50 from the hook 49. The operation of the lever 46 is caused to wind up the spring motor through the agency of a ratchet-wheel 54 and pawl 55.

Title: Control apparatus for television receivers
IPC: H04N5/213
Filed: 1951-07-05
Abstract: 697,821. Television. HAZELTINE CORPORATION. July 5, 1951 [July 21, 1950], No. 15989/51. Class 40 (iii). [Also in Group XL (c)] Relates to means for producing a positive control voltage proportional to the amplitude of the line synchronizing pulses in the receiver of a negative-modulation television system, the control voltage or a fraction thereof being used to bias the synchronizing pulse separator so that the amplitude of the separated synchronizing pulses is substantially independent of fluctuations in signal strength, and a similar negative control voltage being also produced for use as an A.G.C. voltage. According to the present invention, the video signal (including synchronizing pulses and any random noise pulses) is applied to a detector which is gated on by positive pulses derived from the receiver line scan generator, the positive control voltage being developed across a cathode load comprising a parallel RC circuit having a time constant greater than the line scan period. Since the detector is inoperative in the intervals between the synchronizing pulses, the control voltages are unaffected by random noise pulses occurring during such periods. As shown in Fig. 1, the detector comprises. a triode 30 with a cathode load R34, R35 and C33, the positive gating pulses being applied via terminals 29 to the anode and the positive video signal being applied to the grid via terminals 26 and R37 which serves to limit the peaks of the synchronizing and noise pulses. The amplitude-responsive synchronizing pulse separator comprises a high-impedance diode 42 and associated high impedance load R43 coupled between the grid of V30 and the junction of R34 and R35 whose relative values are such that the diode is conductive only during the recurrence of synchronizing pulses, the separated positive synchronizing pulses appearing at terminals 27. A second parallel R.C. circuit R48, C47 in series with a resistor 46 is coupled between the anode of V30 and ground to give a negative control voltage which is applied via terminals 28 to the A.G.C. line. The time constant of circuit 47, 48 is greater than the line scan period and the variable resistor 48 constitutes a contrast control. In a modification, Fig. 2 (not shown), the synchronizing pulse separator comprises a triode with its anode load coupled to terminals 27 and its grid connected to the grid of V30. A circuit, Fig. 3, not within the scope of the present invention, is also described in which the gated detector comprises a pentagrid 52 with the video and gating signals applied to the inner and outer control grids respectively, the negative A.G.C. voltage being derived by coupling the cathode of V52 directly to the grid of a triode 67 having a parallel R.C. load 60 and additional negative synchronizing pulses being produced at terminals 55 connected to the screen grids of V52. Suitable component values are given for the embodiments described and Specification 623,431, (Group XL (c)], is referred to.

Title: Improvements relating to metering pumps
IPC: B67D7/70
Filed: 1931-06-01
Abstract: 379,696. Delivering measured quantities. TECALEMIT, Ltd., Great West Road, Brentford, Middlesex. June 1, 1931, No. 16014. Convention date, May 30, 1930. [Class 102 (i).] In apparatus for delivering measured quantities of oil &c., liquid is supplied from a lower tank to an upper tank 25 by a lift or other pump 2 through passages 23, 24 and filters 26. The liquid flows from the tank 25 to a measuring cylinder 27 when a sleeve valve 30 is i:a its lowest position. When the measuring cylinder and tank 25 are sufficiently full the valve 30 is raised and the measuring cylinder discharges through a pipe 37 fitted with a check valve. The valve 30 carries a rod 29 which is suspended in the piston 10 of the measuring cylinder. Spring-pressed balls 52 in the piston engage a shoulder 29b on the rod 29 on the upward stroke of the piston and the valve is raised if the cylinder and tank 25 are sufficiently full. If, however, the liquid level is low an arm 45 carrying a float 47 engages a knife-edge 42 on a cross-head 39 carried bv the valve and rise of the valve is prevented. In a modification, Fig. 6, the valve 30 is provided with a check-valve 60. If the liquid level is low the stem of the valve 60 is engaged by a lever 45 carrying a float 47 and, on the rise of the piston of the measuring cylinder, the liquid is forced back into the tank 25. If, however, the liquid level is sufficiently high, the lever 45 is disengaged from the valve 60 and the valve 30 is raised by the liquid in the cylinder 27, which is discharged through the outlet 37. The piston 10 of the measuring cylinder is connected by a rod 3 to the lift pump, which may comprise a piston 2, movable on the rod, and co-operating with a disc 6 to form a valve. An arm 13 is formed with a crank 12, pivoted in the rod 3, and with a crank 14, pivoted in an arm 16 and carrying a pinion 15. The latter gears with a pinion 18, also carried by the arm 16, and gearing with a fixed pinion 20. The arm 16 is carried by a spindle 17, operation of which by hand or motor causes straight-line movement of the rod 3. The valve 30 co-operates also with indicating mechanism comprising a pointer 78 on a spindle carrying an escapement wheel 72. A double-armed pawl 70 engages a deep notch 73 in the wheel 72 when the pointer is at zero. In this position the tail -74 of the pawl engages the arm 40 of the crosshead 39 and locks the valve 30 in its lowest position. When the pointer is set for discharge of any quantity, the tail 74 is inclined and is operated bv the movement of the arm 40 until the pointer 78 returns to zero. An arm 43 in the crosshead 39 operates a counter 44.
